Strobe signal to latch externally the lower address information which is output to PD7 to
PD0 pins to access external memory. When RESET signal is either low or in the hardware
STOP mode, this signal becomes output high-impedance.
Strobe signal which is output for write operation of external memory. It becomes high in
any cycle other than the data write machine cycle of external memory. When RESET signal
is either low or in the hardware STOP mode, this signal becomes output high-impedance.
Strobe signal which is output for read operation of external memory. It becomes high in any
cycle other than the read machine cycle of external memory. When RESET signal is either
low or in the hardware STOP mode, this signal becomes output high-impedance.

PB7 to PB0
(Port B)
Receive Data
Input pin for serial data.
Input-output/
Input
Transmit Data
Output pin for serial data.
Serial Clock
Input-output pin for serial clock.
It becomes output clock for the internal
clock use, and input for the external.
Interrupt Request/Timer Input
Maskable interrut input pin of the edge
trigger (falling edge), or an external clock
input pin for a timer. Also, it can be used
as a zero-cross detection pin for AC
input.
Timer Output
Square wave defining one cycle of internal
clock or timer counter time as half cycle
is output.
Counter Input
External pulse input pin to timer/event
counter.
Counter Output 0, 1
Programmable rectangle wave output by
timer/event counter.
Address/Data Bus
When external memory is used, it be-
comes multiplexed address/data bus.
Port D
8-bit input-output port, which can specify
input-output in byte units (
μ
PD78C11A).
Port F
8-bit input-output port, which can specify
input-output bit-wise.
Address Bus
When external memory is used, it be-
comes address bus.
Port C
8-bit input-output port,
which can specify input/ output bit-wise.
